Does anyone recommend a home made moss remover from slabs and patio?

Straight vinegar. Give it a good spray and let it soak in. Then hose off the area.

Vinegar! In a spray bottle, as strong as you can stand it, and 100% Raw Vinegar. Vinegar repells insects of all kinds, weeds,

Wet and Forget

50/50 bleach and water solution in a spray bottle

Listen to me now. Forget the vinegar. "Spray and Forget" is the product. Don't expect results right away but I sprayed the black stuff on my siding 5 years ago when I moved in and it still looks white. Sprayed it on my patios, front and back and they still have very little green. May be time for a respray.

Thank you
